bore 2 8'f`lead's" from" each "opening 24 radially`throii'gh thev web'19, said boltfextends spring 31 seated beneath said shoe and in a seat on the exterior of said drum.

A gear 32 is fastened to the face of the pulley sleeve 15,' as by means of screws 33, and a similar gear 34 is keyed to the shaft. Pinions 35 are pivotally mounted on web 19 in mesh with the pulley gear and idlers 36 are also pivoted to said web in mesh with the shaft gear, each idler meshing with one of said pinions.

- Theflgyferfgis connected at its outer end to a pair.l of links 37 which have a pair of links 38 pivoted between them, which in turn are pivoted to an arm 39 of a collar 40 slidably mounted on the shaft 11. A plurality of these arms, links and levers are provided, and a closing plate41 seats against the outer rim ofthe drum, forming a housing therewith for the gears, and contains slots 42 in which the levers 25 operate. A

' groove 43 is formed around said collar in which operate shoes 44 attached to a yoke 45 of a lever 46, which is'pivoted at its middle portion to a bracket 47 fastened to the support 10, and has a slot 48 at its lower end.

An operating member 50 is pivotally connected, by means of a pair of links 51 and a pin 52, to one corner of a triangular plate 53, which is pivotally mounted on a pin 54 fastened on a curved bracket 55 attached to the support 10. Threaded members 56 are pivoted to the other corners of said plate 53 and have their free ends fastened each to an end 57 of a brake band 58 engaging around the drum 17. The member 50 is provided with a side lug 59 to which is pivoted one arm 60 of a bell crank pivoted at 61 to the bracket 55, the other arm 62 of the bell crank engaging in the slot 48. A disc 63 is mounted on said shaft, adjacent the closing plate 41.

In operation the member 50 is thrust forward toward the device which carries the arm 60of the bell crank forward and moves the free end of the crank arm 62 towards the right, as viewed in Fig. 3, carrying with it the lower part of the lever thereby forcing the sleeve and the toggle inwardtowa-rd the clutch. This action brings the connected ends of the links 37 and the associated links 38 against the disc 63, the links 38 slanting inward towards said disc. The further inward movement of thecollar 40 straightens out these links 38 forcing them in a direction radial to the shaft, thereby drawing the links A37 andthe outer ends of the levers 35 inwards toward the shaft. The heads 27 of the bolts 26 will act as fulcrums for the lever forcing the bolts inward and with them the shoes 29-into contact with the flange 16 of the drum, at the Sametime the inner ends of the levers will force the shoes 21 outwards toward the inside of said flange 16. During said movement of the clutch operating mechanism plate 53 has been partly rotated upon the pin 54, thereby separating the ends 57 of the band 58 and loos ening said band upon the drum 17, shown in Fig. 5. With the members in this position, the clutch spider of the drum engages the ange of the pulley and Athe drum and pulley rotate together. The gears and pinions mounted on the shaft, pulley and drum will lock the shaft with the pulley and force the Ishaft to also rotate in unison with the drum and pulley, that is, all members rotate in a forward direction. When the operating member 50 is drawn outwarus the co1- lar 4() is drawn away from the drum and toward the support and the clutch members are released from the flange of the pulley. At the same time the plate is partlv rotated upon the pin 54 bringing the ends 57 of the brakeband 58 together and thereby tightening said band upon the drum to hold the drum against rotation. The rotation of the pulley will now carry with it its attached gear 32 which will rotate the pinion-s 35 and through them the idlers 36 meshing with the gear 34 keyed to the shaft. The arrangement of these gears,pinions and idlers will rotate the shaft in a direction reverse to that of the pulley.

It is thus evident that by an inward thrust of the operating member 50 the clutch members become operative and the brakeband is released, and the pulley, drum, shaft and associated members rotate in unison;

and that by an outward thrust of the operating member 50 the clutch members are released andthe brake-band engages the drum and holds the same, whereupon the pulley and Ishaft rotate in reverse directions.

It will be noted that when the reversing mechanism is in operation the clutch members are stationary and consequently adjustment thereof may be made by means of the nuts 30. This is a very important feature in that clutches are ordinarily used with explosive engines and the adjustment can thus be made as necessary without stopping the engine.

It will'also be observed that the entire belt strain on the pulley is only the fly wheel support and is thus sustained by the engine bearings. Inasmuch as these belts are usually of considerable length and carry the load this construction is preferable. Also by the placing of the driving pulley next to the fly wheel to which the clutch is lattached., the gears and operating mechanism are arranged on the outside of the clutch so that they can be readily removed by the removal of the outboard bearing alone.

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the lll() rpmcisedetailsrof theconstrudtion set forth,
